What oil should I use? 1st oil change after rebuild...

[Silver400EXinBR]

I just got my bike back from doing everything in my sig. I just finished running a little over a tank of gas through it. I know I should change the oil now. What is the best oil I hould put back in it and what is the best to keep running in it also. I would appreciate all the info I can get on it.

I just got my engine back from ct racing and he told me to run redline synthetic. He said 15-50 but i can't find 15 weight so i run 20-50 it runs awesome!

many people prefer mobil 1 15w-50. only use this after the motor is fully broke in though.

I thoughtit wasnt good to run a synthetic oil in a motor that was just built.. I have had my bike a week and burned 1 full tank of gas..... How long does it take to fully break in? SO is it better tio run synthethic or not synthetic??

[cals400ex]

i would put in more non-synthetic this time, but others would do the opposite. i am just want to make sure it is fully broke in before i switch.

after about a half a tank of gas i put in castrol 20w 50.. then once i put about 2 tanks of gas threw that.. i put in um....
castrol syntec 20w 50 full synthedic runs execelent

Sorry, my bad i didn't explain myself very well. I meant after the cam breaks in. Synthetic is way to slipppery for break in, i used petro based 10 weight for break in but after my whole break in procedure i changed oil. Sorry for the misunderstanding
